Question 4

Mathematics
1 answer:
Alex_Xolod [135]3 years ago
6 0

Answer:

8

Step-by-step explanation:

1.) d=\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

       (-6, 7) is now point 1

2.) -6 = x_{1} & 7 = y_{1}

        (-1, 1) is now point 2

3.) d=\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

4.)d = \sqrt{[-1 - (-6)]^{2} + (1-7)^{2} }

5.)d=\sqrt{(5)^{2} + (-6)^{2} }

6.)d=\sqrt{25+36}

7.)d=\sqrt{61}

8.)d≈7.8

7.8 rounded to the nearest whole is ROUGHLY 8

hope this helped ^∀^  ¬ω¬

A series of three? separate, adjacent tunnels is constructed through a mountain. Its length is approximately 25 kilometers. Each
Nadya [2.5K]

Answer:

312.5\pi \text{ km}^3\approx 981.75\text{ km}^3

Step-by-step explanation:

We have been given that a series of 3 separate, adjacent tunnels is constructed through a mountain. Its length is approximately 25 kilometers.

Each of the three tunnels is shaped like a half-cylinder with a radius of 5 meters.

Since we know that volume of a semicircular or a half cylinder is half the volume of a circular cylinder.

\text{Volume of a semicircular cylinder}=\frac{\pi r^2h}{2}, where,

r = Radius of cylinder,

h = height of the cylinder.

Upon substituting our given values in volume formula we will get,

\text{Volume of a semicircular cylinder}=\frac{\pi (5\text{ km})^2*25\text{ km}}{2}

\text{Volume of a semicircular cylinder}=\frac{\pi*25\text{ km}^2*25\text{ km}}{2}

\text{Volume of a semicircular cylinder}=\frac{\pi*625\text{ km}^3}{2}

\text{Volume of a semicircular cylinder}=\pi*312.5\text{ km}^3

\text{Volume of a semicircular cylinder}=\pi*312.5\text{ km}^3

\text{Volume of a semicircular cylinder}=981.74770\text{ km}^3

Therefore, the volume of earth removed to build the three tunnels is 312.5\pi \text{ km}^3\approx 981.75\text{ km}^3.
